The alternator malfunctions because it produces an inadequate voltage or inadequate voltage due to prolonged use. The battery warning light flashes as a result of this. Changing the faulty alternator out for a new one is the simplest solution to the problem.

Battery Problems

After three to five years, you should replace your BMW battery. Your driving habits, vehicle maintenance, and a number of other factors will all affect how it is.

Using Additional Electronics

The new electronic component is to blame if you notice a decrease in your car’s performance after installing it or after connecting a phone.

Computer Error

The battery light may turn on from time to time, and you might not be able to think of a good reason for it. It indicates that there is a programming error on the computer in your car. To fix the problem, all you have to do is reset it.

How To Fix The BMW Charging Malfunction?

  • Step 1: In order to check the battery voltage, you must first purchase a voltmeter. Positive and negative battery terminals on your car should be connected to the voltmeter.
  • Step 2: Measure the voltage after turning the car off. Your vehicle is in good condition if it displays between 12V and 12.5V. The battery is weak or the alternator cannot charge sufficiently if the reading is less than 11.5, though.
  • Step 3: For greater assurance, measure the voltage both when the engine is running and when it is idle. The battery and alternator are functioning properly if it produces 13.5 to 14.5V. The battery and alternator are unable to function properly if it is either below or above these values.

Alternators and batteries need to be replaced if they are the root of the problem. In order to replace those, it will be advisable to bring your car to a nearby mechanic shop. However, if you want to replace the alternator by yourself, pay attention to the visual instructions.
